1. 16. Sense of coherence (SOC) in women treated for breast cancer and its relation to treatment outcome

   Författare :Carina Lindblad; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Breast cancer;

   Sammanfattning : Breast cancer incidence has, on average increased by 1.4 % annually during the last decades. Early detection and advances in treatment are the main contributing factors for the favourable outcome in terms of five- and ten-year survival rates. LÄS MER

3. 17. Modeling Realized Covariance of Asset Returns

   Författare :Gustav Alfelt; Joanna Tyrcha; Taras Bodnar; Tatjana von Rosen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical Statistics; matematisk statistik;

   Sammanfattning : In this thesis, which consists of two papers, we consider the modeling of positive definitive symmetric matrices, in particular covariance matrices of financial asset returns. The return covariance matrix describes the magnitude in which prices of financial assets tend to change over time, and how price changes between different assets are related. LÄS MER

4. 18. Exploration of novel mechanisms and biomarkers for venous thromboembolism : a genetics and proteomics study

   Författare :Maria Bruzelius; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Venous thromboembolism (VTE) contributes to a large health burden and incidence increases exponentially with age. ~25% patients will experience a recurrent event and there is a 2-fold risk for death in the following years. Risk prediction remains a challenge. LÄS MER

5. 19. Interpretable machine learning models for predicting with missing values

   Författare :Lena Stempfle; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; missing values; Machine learning; healthcare; interpretable machine learning;

   Sammanfattning : Machine learning models are often used in situations where model inputs are missing either during training or at the time of prediction. If missing values are not handled appropriately, they can lead to increased bias or to models that are not applicable in practice without imputing the values of the unobserved variables. LÄS MER

7. 20. Experiments and simulations of lean methane combustion

   Författare :Jenny Lindberg; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

   Sammanfattning : Computational fluid dynamics of methane combustion using chemical kinetics for description of the chemistry is studied. Linear least squares data fit to measured concentrations and temperatures is used to modify reaction rate parameters in the Arrhenius rate equation for combustion of methane. LÄS MER
